<p class=MsoNormal><font size=2 face=Arial><span lang=EN-GB style='font-size:
10.0pt;font-family:Arial'>The changes to vtkDataSetSurfaceFilter from 1.30 to
1.35 have had some undesired side effects with the display of quads attached to
hex faces (quads coincident with faces using the same point id’s). In version
1.30 it appears that all the 2-d cells were drawn after the 3-d cells so the
quads were never hidden by the hex’s. In version 1.35 this discipline appears
to have changed with some of the 2-d cells shown but others obscured by the 3-d
cells.</span></font></p>

<p class=MsoNormal><font size=2 face=Arial><span lang=EN-GB style='font-size:
10.0pt;font-family:Arial'>Does anybody know how I can arrange to draw the faces
of all the 3-d cells first, followed by all the 2-d cells? Should this be the
responsibility of the application developer or VTK?</span></font></p>

checking FE-models where boundary elements are connected to finite elements or where
there is a transition from 3-d to 2-d elements.</span></font></p>
